Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of lifting travel switch stop means is provided, and obtains more reliable and more stable information acquisition ability, makes debugging and safeguards more convenient.
The technical scheme that provides according to the utility model; Said lifting travel switch stop means; Characteristic is: comprise the deep groove ball bearing and the axle that are installed in the axle bed, stretch out outside the axle bed at the two ends of said axle, through flat key the first wheel and second wheel hub is installed at an end of axle; Surface at the said first wheel and second wheel hub offers annular mounting groove, in the annular mounting groove of the first wheel and second wheel hub, collision block is installed respectively; The travel switch holder is installed on said axle bed; The travel switch mount pad is installed at two ends at the travel switch holder respectively; The travel switch mount pad is provided with travel switch, and said travel switch and first wheel, second wheel hub are positioned at the same side of travel switch holder.
Between said axle and axle bed, be provided with oil sealing and back-up ring.
Porose in the arranged outside of said deep groove ball bearing with circlip, little round nut and O RunddichtringO.
On said axle, be covered with cover, the top of said cover is through stent support, and support is fixing with cover through the 3rd hex bolts, Siping City's packing ring.
Shaft end in that first wheel one end axle is installed is equipped with shaft-cup.
The utlity model has following advantage:
(1) stable, reliable, the machine error of generation is little;
(2) the position relative fixed of each device can not slided or phenomenon such as loosening because of As time goes on producing;
(3) be more prone to regulate and safeguard,, only need carry out the shift position during adjusting and can regulate collision block through the annular slot above the wheel hub.
Description of drawings
